ANS designates Armour Research Foundation Reactor as Nuclear Historic Landmark
The American Nuclear Society presented the Illinois Institute of Technology with a plaque last week to officially designate the Armour Research Foundation Reactor a Nuclear Historic Landmark, following the Society’s decision to confer the status onto the reactor in September 2024.

The task of the theory of tokamak equilibrium is to determine the global magnetic confinement topology and physical characteristics of the underlying basic equilibrium state, which is assumed to be static (both [partial derivative]/[partial derivative]t = 0 and background velocity v0 = 0). This could be considered to be the most boring case of plasma behavior, viz. total absence of dynamics: a corresponding fluid dynamics problem hardly exists. The reason for our interest in this plasma state is the prospect of obtaining clean, abundant, and cheap energy from controlled thermonuclear fusion reactions. Of course, criticism and doubt immediately enter the mind after a statement like this. Nevertheless, let us study this plasma state, leaving questions like 'is there such a state at all?' and 'is it actually so desirable?' for later (Sec. 5).
